Application filed July 2, 1914.

To all whom it may concern Be it known that I, HENRY COI-IIC, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Umbrellas, of which the following is a specification.

This invention relates to umbrellas of the folding type, and its object is to provide a novel and improved umbrella of this type which is also self-opening.

The invention consists in a combination and arrangement of parts to be hereinafter described and claimed, and in order that the invention may be better understood, reference is had to the accompanying drawing, in which- Figure 1 is an elevation of a fragment of the umbrella in open position, only one of the ribs and parts associated therewith being shown; Fig. 2 is an elevation showing the umbrella closed; Fig. 3 is an elevation showing the umbrella folded; Fig. 4: is an elevation, partly in section, showing the joint between one of the ribs and its stretcher; Fig. 5 is a sectional detail on the line 55 of Fig. 4, and Fig. 6 is a section on the line 6--6 of Fig. 1 showing the joint between the stick sections.

Referring specifically to the drawing, the stick of the umbrella is in two sections denoted at 10 and 11 respectively, the former carrying a detachable handle 12 which is coupled to the stick section by a suitable catch 13. The stick section 11 carries at its outer end a tip 14. The stick sections are foldably connected, and the tip is foldably connected to the stick section 11.

The foldable connection or joint between the stick sections 10 and 11 is made as follows: Both stick sections are hollow, and the section 10 carries a short projecting stem 15 which is screw-threaded to screw into the section 11, as shown in Fig. 6. The screw stem is secured to the section 10 by a cross pin 16, or any other suitable means. In the hollow of the section 11 is slidably mounted a retaining member 17 having a head or abutment 18 at its inner end which cooperates with a stop lug 19 in the section 11 to limit the outward travel of said member. The outer end of the retaining member is connected by a pivoted link 20 to the outer extremity of the screw stem 15.

The stick sections 10 and 11 are coupled together by screwing the stem 15 into the Specification of Letters Patent.

section 11. To uncouple the stick sections, the section 10 is rotated to back the stem 15 out of the section 11. The section 10 is then pulled away endwise from the section 11 until the link 20 is on the outside, after which the two sections may be folded alongside each other, as shown in Fig. 3. The parts 18 and 19 prevent the member 17 from being entirely withdrawn from the section 11. A foldable connection as herein described is also provided between the tip 14 and the stick section 11, the link corresponding to the link 20 being indicated at 21., and

the screw stem corresponding to the screw stem 15 being indicated at 22, said stem 22 beingcarried by the stick section 11 to screw into the tip, which latter is made hollow and internally screw-threaded for this purpose.

Adjacent to the outer end of the stick section 11 is mounted a collar 23 to which the ribs of the umbrella are pivoted as usual. The ribs are each composed of two pivotally connected sections indicated at 24 and 25, respectively, the former being the inner section, while the latter is pivotally connected at its inner end to the collar 23. The stretchers 26 for the ribs are pivotally connected at the inner ends to the usual runner 27 which is slidable on the stick, and the latter carries the usual catches 28 for the runner. The cover, which has not been shown, is secured in the ordinary manner.

The stretcher 26 is pivotally connected to the inner end of the outer rib section 25, said end being reduced in width, as indicated at 29, to fit in a slot 30 in the outer end of the stretcher. A pin or rivet 31 passing through these parts provides the pivotal con nection therebetween. he rib section 2 L is connected at its outer end to the inner end of the rib section 25 by a pin or rivet 32, the outer end of the rib section 24 being slotted, as indicated at 33, to accommodate the reduced inner end 29 of the rib section 25. Both rib sections are channeled in crosssection, and the reduced inner end 29 of the rib section 25 seats partly in the channel of the rib section 2% when said rib sections are placed in alinement.

The pivot 32 of the rib sections 2 1 and 25 is slightly in advance or outward of the pivotal connection 31 between the stretcher 26 and the outer rib section 25, and a short distance back of said pivotal connection 31 one end of a coiled spring Si is fastened to the stretcher, the other end of said spring and when being connected the rib section adja-i pivotal connection with the colmatically open the umbrella as will be pres-.

ently described.

The outer end of the stretcher 26, adjacent to its pivotal connection 31 with the rib section 25, has a cam-like bend 35 toward.

the rib section 24, said bend abutting against the under side of the latter rib section when the umbrella is open, for a purpose to be hereinafter described. V

Fig. 2 shows the position of the parts when the umbrella is closed. The springs 34 are now under tension so that when the lower runner catch 28 is operated to release the runner 27, the latter is pulled upward and the stretchers swing outward to open the ribs. The upper runner catch 28 limits the upward sliding movement of the runner, said catch stops the runner, the stretcher and the ribs are in full open position. The umbrella is closed in the ordinary manner by pulling the runner 27 down on the stick until it is engaged by the lower runner catch 28. This downward movement of the runner stretches the opening springs 34 and places the same under sufficient ten sion to effect the automatic opening of the umbrella hereinbefore described, when the lower runner catch 28 is operated to release the runner. By attaching the springs 34: a short distance back of the pivotal connection 31 between the rib section 25 and the stretchers 26, and locating said pivotal connection back of the pivotal connection 32 between said rib section and the rib section 24, the automatic opening of the umbrella is assured, as the pivots are not in dead center positions when the umbrella is closed, and there is consequently no danger of the parts sticking or binding. The slots 33 and 30 allow the parts to fold close.

The umbrella is folclable from open position in the following manner: The runner 27 is advanced slightly beyond the upper runner catch 28 upon disengaging said catch, as

shown dotted in Fig. 1. This movement of the runner brings the stretchers nearer to a position at right angles to the stick than when in position to hold the ribs open, and consequently the pivots 31 move outward,

, with the result'that the rib sections 25 swing upward about their pivots 32, as shown dotted in Fig. 1. The cam surfaces 35, by their engagement with the under side of the rib sections 24, assure a flexure at the joints 32. After the rib sections are partly foldeclas shown folded by hand to completely folded position as shown in Fig. stretchers and the rib section come close together, and the umbrella, after folding the stick as hereinbefore described, is now in small compact form.

The structure is simple and devoid of complicated parts liable to get out of order, in view of which the umbrella can be cheaply manufactured, and the herein described op eration is reliable, and the same is readily effected. The rib sections are in perfect alinement when the umbrella is open and the joint between the sections is smooth so that there is nothing to detract from the appearance ofthe umbrella.

Iv claim: I V I V In an umbrella, av stick, a runner on the stick, sectional ribs conslsting of inner and outer pivotally connected sections, the outer rib section having its inner end extending back of the pivotalconnection, and stretchers connected to said inner ends of the outer rib sections, the outer ends of the stretchers adjacent to their pivotal connection with the outer rib sections having a cam surface for flexing the rib sections at their pivotal connection, said cam surface engagingthe under side of the inner rib sections when the umbrella is open. 7 V
